Abstract

A unique trinuclear centrosymmetric zinc(II) complex, [Zn3L2(CH3CO2)2(DMSO)2] has been synthesized and characterized by using a reduced Schiff base ligand H2L {H2L = 1,3-bis(2-hydroxybenzylamino)2,2-dimethylpropane}. The complex has been characterized by spectral and elemental analysis. Single crystal X-ray diffraction analysis has confirmed the structure of the complex. The complex has showed strong fluorescence, which may be quenched in presence of different nitroaromatic substances. The complex thus used as a sensor for the detection of nitroaromatics in DMF via turn-off fluorescence response.
